How far away will the RM remote still control the SM transmitter? Can I amplify the tones for more range? Open


The range is not really limited by how loud the RM is or how the gain is set on the SM though these do have some affect. The limit on range is reflections from other surfaces. This effectively limits the range to 8 feet or less with maximum output on the RM and maximum audio gain on the SM. Even outdoors this short range is true since generally both the talent and the operator are standing on the ground and this is a reflective surface. The reflections cause the SM to receive echos of the transmitted tones so that the SM is trying to decode the proper sequence of tones and a delayed version of the tones. Amplifying the tones does no good at all since it is reflections that cause the failure of the decoding.

There is a positive aspect to this in that it is difficult for one RM to activate two transmitters at once which could lead to unintended results. More importantly, some prankster can't play the tones through the PA system and cause havoc. It is possible to to play the tones through a 2 way radio and allow very remote control. Cell phones don't work very well in this application due to the large amount of signal distortion (destruction?) that goes on.
